So one thing I’ve wanted to talk to the community about for a while is the new input system we’re working on in PNH. This new version (yet another one) fixes recently detected errors and adds some. When the fio IO thread is migrated to new CPU, the same steps can be repeated again. The migrate period can be %d", args->comm,args->pid,args->orig_cpu,args->dest_cpu' | grep fio For test b), I thought that load balance may be triggered when single fio IO thread takes the CPU by 100, meantime XFS's queuework() schedules WQ worker thread on the current CPU, since all other CPUs are idle. It is found that single AIO thread is migrated crazely by scheduler, and Jens Axboe, Ingo Molnar, Peter Zijlstra, Tejun Heo To: linux-block, linux-fsdevel, linux-xfs, linux-kernelĬc: Jeff Moyer, Dave Chinner, Eric Sandeen, Christoph Hellwig, 23:54 ` Dave Chinner 0 siblings, 2 replies 66+ messages in thread Single aio thread is migrated crazily by scheduler All of help / color / mirror / Atom feed * single aio thread is migrated crazily by scheduler 11:31 Ming Lei CHK File Recovery is a tool that can be used in the event that an important tile is lost or otherwise hidden from view.
